【正确答案】As the basic and dominant industry, the real estate industry develops into the process of the continuous adjustment. From the middle 1950s to the early 1980s, there didn't exist the real estate market in China. During that period, the allocation of land and house resources was under the plan of the government instead of the real estate market which was cancelled. Therefore, China's real estate industry has been only growing up for 20 years since 1980s and entering into the period of development with steady steps. However, it has also undergone the cycle fluctuation of revival, boom, recession and depression.
